river navigation

River navigation involves guiding ships and boats through waterways using natural features and navigational tools. It requires understanding the river’s depth, currents, and obstructions to ensure safe passage. Navigators use charts, sonar, and buoys to determine the best routes and avoid hazards like rocks or shallow areas. Tides and weather conditions also influence navigation, affecting water levels and currents. Proper planning and the use of aids like signaling systems help ensure safe, efficient movement of vessels along rivers for transportation, commerce, or sightseeing.
